A groove and several longitudinal holes are disposed on each outer lateral side of the plastic frame. And the longitudinal holes are arranged to the top of the lateral side of the frame. On the bottom of groove, several pairs of bilateral hole are mounted thereof, penetrating the lateral side of the plastic frame to reach the above mentioned longitudinal holes. On both lateral sides of each metal plate, a downward folding rim contains several fasten teeth corresponding to each longitudinal holes of the plastic frame, and each tooth has a buckle hole. The lateral metal bar is used to affix at the groove of both sides of the plastic frame. Several fingers are arranged perpendicular to both edges of the lateral metal bar and corresponding to the buckle holes on metal folding rim of the metal plate. The finger has a protruding bead on the center thereof. In accordance with the structure mentioned above, the PC board is mounted into the plastic frame first and the two metal plates are covered on the PC board. Afterwards, the lateral metal bar is arranged on the groove of the plastic frame and then the fingers are inserted into the corresponding bilateral hole, penetrating the lateral side of the plastic frame to reach the above mentioned longitudinal holes. The protruding bead can be fastened with the buckle hole.
When in use, NIC frame in accordance with the present invention can be easily dismantled by buckles and fingers. In addition, the PC board inside the NIC frame of the present invention is double-protected by the two lateral metal bars clamped on the sealed edge of the two metal plates.
